Claims.

This invention relates to pintle retaining means for journal boxes and comprises a tubular lining member removably fitted in one of the pintle sleeves of the lid and having a series of bendable pintle retainin tongues at its outer end. The companion sleeve of the lid is flanged or closed at its outer end to provide abutment which prevents axial displacement of the inserted pintle in one direction, axial displacement of the pintle in the opposite direction bein prevented by bending one or more tongues of the lining member to a retaining position opposite the remaining end of the pintle.

There is a lid now on the market provided with bendable pintle retaining tongues formed integral with the outer ends of the pintle retaining sleeves but this construction has the disadvantage that the lid, as a whole, must be replaced when the tongues are broken oil by repeated bending and straightening operations to which they are subjected incident to application and removal of the lid. Another objection to this construc tlon is that it is more or less limited to lids of the stamped or sheet metal type. As compared with this prior construction the pintle retaining liner 5 of the present invention constitutes a separate unit which may be applied to either stamped or cast metal lids and is replaceable at a relatively small cost.

Proceeding now to a more detailed description of the invention, reference will be had to the accompanying drawing wherein Fig. 1 is a fragmentary sectional view of the lid and body portion of a journal box secured together by a hinge connection including a pintle retaining liner applied in accordance with this invention.

Fig. 2 is a view in elevation of the pintle retaining liner as it appears prior to its application to the lid.

Fig. 3 is a longitudinal section through the pintle retaining liner.

Referring more particularly to the drawing, 11 designates a journal box lid equipped with pintle sleeves 12 and 13 aligned with the pintle lug 14 of the body portion 15. The outer end of sleeve 12 is provided with an annular flange 16 forming an abutment for one end of the inserted hinge pintle 17. The companion pintle sleeve 13 is provided with a tubular liner 18 removably fitted therein. The inner end of the liner is provided with a flange 19 which holds it against outward movement through the sleeve 13. The outer end of the liner is cut to provide a series of tongues 20 projecting beyond the adjacent end of sleeve 13.

One of these tongues is adapted to be bent, as indicated by dotted lines in Fig. 1, to lie in a retaining position opposite the adjacent end of the pintle 17, so that the pintle, being trapped between the bent tongue 20 and the flange 19, is

securely held against axial displacement in either direction. When the pintle is to be removed the bent tongue 20 is straightened to a position clear of the adjacent end of the pintle so that the pintle may be driven outwardly through the sleeve 13. Since the retaining tongues 20 are apt to break .off after being subjected to several bending and straightening operations a series of such tongues are provided so that when one is broken another may be brought into use. In this way, the useful life of the pintle retaining liner is extended over a' relatively long period. When all of the tongues are broken oil the liner may be removed and replaced at a relatively low cost.

The liner 18 preferably comprises a drawn seamless tube having one end enlarged to form left entirely open at its outer end and provided with a pintle retaining liner similar to that shown in connection with the sleeve 13. This last construction has the advantage that the liners take the wear of the pintle and may be replaced at relatively small expense when worn to the point where they are no longer serviceable.

Having thus described my invention, what I claim is:-

1. The combination with a journal box lid having aligned pintle receiving bores, of a tubular liner fitted in one of said bores and having one or more bendable tongues at its outer end projecting beyond the corresponding end of said bore.

2. The combination with a journal box lid equipped with aligned pintle receiving sleeves of a tubular liner fitted in one of said sleeves, a flange at the inner end of the liner engaging an adjacent portion of the lid to prevent outward movement of the liner through said sleeve, and one or more bendable tongues at the outer end of the liner projecting beyond the corresponding end of said sleeve.

3. The combination with a journal box lid of a tubular liner fitted in one of the pintle retaining at both ends and having one end cut or notched to provide a plurality of bendable pintle retaining tongues.

5. A pintle retaining liner adapted to be inserted in one of the pintle receiving bores of a journal box lid comprising a thin metal tube having a flange at one end and a series of V- shaped notches extending inwardly from the opposite end.
